Do I have too many fish for a 10 gallon aquarium?

WAY too many fish. What kind of loaches are they?

It looks like you have too many fish for a 20 gallon tank.

Tiger barbs get too big for 10 gallon tanks, the chinese algae eater can get to be 10 inches long and very aggressive when older, some loaches stay small enough for a 10 gallon but most need at leats a 20 gallon and some need a 75 -100 gallon tank. But the puffer may just eat many of your fish so that may not be a problem.

Yes, that's too many fish for a 10 gallon tank.

The red eye puffer is likely fine for now, but may get aggressive as it matures. For juvenile fish, the tank is okay--not great, but okay. As the fish grow, they will begin producing more waste, and compete for territory, causing fights and other stress related problems. Stunting is likely as well.

awefull lot of fish for a 10-gallon...on what I've read, no more than about 10 1-inch fish for a 10-gallon tank, but if you're more experienced, you can go more...

I am still a newbie myself, and I have been doing a LOT of reading...

The optimal tank for a newbie is at least a 30-gallon, but the bigger the better...

I hate to jump on the bandwagon with everyone else, but they are on the right wagon. Far too many fish, and a really difficult combo. I'm not an authority on puffers So I'll let someone else weigh in on that, but Tiger barbs are IMO and IME extremely dangerous in a crowded tank, they will adjust the population to their liking eventually. If the other fish like the puffer let them live long enough. The mollies will have the most trouble, If you removed everything else, added a couple of cories the mollies would be OK in a 10g everything else involved needs a bigger tank.
