Not an expert, but I'd question whether they've worked themselves outward or were never hammered home in the first place.
Thinking nails in this application are for shear strength and not lateral loads. Might just make it worse and accelerate the joist splitting by hammering them in now.

You should replace them with the correct nails. There are nails specifically for joist hangers and those are not it. I see at least 3 different kinds of nails used in yours, none right. They will be sold under the simpson strongtie brand as connector nails, 10d, Strongtie also has some connector screws out now. Never use any other type of screws with joist hangers.

I agree with firebrick but might look at the screws made for joist hangers.

On my deck I used Screws sold by Simpson specifically for use with joist hangers. far easier and faster than nails IMO.

If I was going to replace nails, I'd sure have my palm nailer and compressor out.

Standard nails (not simpson brand) are fine as long as you use the correct size. The reason simpson sells those special nails is because they are only 1-1/2” long but still the correct diameter to carry the load. Being that short,they don’t poke out the other side of the joist.

No, they are not.
The "penny nail size" is more related to length and weight of a 1000 nails than diameter. Common 10D nails can come in .120, .128, and .148 diameter. Most are not hot dipped galvanized either like connector nails.
Most connector nails are .148 diameter hot dipped galvanized.
On top of it they have a symbol on the head. They are designed as a system and many code jurisdictions check briefly to ensure that the proper nails have been used. Also most code is written to state that connector systems are ok to use(or even the only thing to use) but you must follow the companies instructions which state the number and size/style of nail which they will only state theirs as they have done the engineering on it.
If you build something that collapses and you installed non compliant components you open yourself up to all sorts of legal issues.

Even the correct joist hangar nails will back out. It isn’t unusual at all. Better than nothing, hammer them back in. Better, replace them with screws or longer nails. Once they back out, they will never be sufficiently tight again to hold.
I doubt the nails were ever driven all the way home . leave them or put in proper hanger nails

They make screws for that.

May not be right diameter. I think you may want the #9 or #10 - for either 10 penny or 16 penny nails. Need to know what joist hanger was designed to for. Guessing the #10/16 penny nail.

Yes they are. Here is a screen shot from the Simpson page.

They are showing the high-dollar proprietary fastener … marketing!
No, those are not the right screws. Too big for the hangers. It will be the SD screws, not the SDS. Probably a #10 but it could be a #9. Do you know what the hanger number is? Or even the the size of the hanger? I can look it up for you. And the SD screws will either be 1-1/2 or 2-1/2". Obviously if it's a single 2x it will only take the 1-1/2"
This is a list of all the connectors and the SD screws they can use.

Holy ****. Who knew all that went into joist hanger hardware. I am learning.

You'd be surprised how many guys would rather run the SD screws than hammer nails all day. We sell a lot of those.
That's the easy part. You'd be surprised how crazy it gets with all the different hardware, connectors, hold-downs, etc. I'm not a contractor, I work for a building supply place. We don't sell lumber, doors, or windows. But we sell more Simpson-Strongtie than anyone else in the area. That's our main product line.

Haven't built decks for years, but I recall the joist hanger nails were called tico nails? I'm sure I have some boxes of them, along with boxes of other stuff I'll never use...
