I have a bike that has a 5spd cassette on the back wheel. The front has 2 rings making the bike a 10 spd. It's difficult to find a 5spd cassette online. Could I get a 7, 9 or 10 speed cassette assuming it would fit on the hub? Would I need to get new shifters also?

Your question is actually about a freewheel which is VERY different from todays modern drivetrain which indeed are cassette's. .
SIMPLY PUT... There is NO SUCH of a thing as a 5 or 6 speed cassette - rear spacing COULD be 126mm or 130mm for a road bike - that being said, Durace 10 speed is in the 130mm spacing, just like a 5 or 6 speed from just as early as the mid-80's. Your bike will not hold a cassette, It's a freewheel.
You would have to change out so much stuff it would not be cost effective to do it -especially if you don't work in a shop.

Actually the reason you can't replace your 5 speed with a 7,8, or 9 speed etc. is because one the hub you have now will not accept the new cassette because of its width if it 's in-fact a cassette and not a freewheel.
Your stays( mounts ) also will not accept the width of the 7,8, or 9 speed hub.
If you have a freewheel and you could find a 6speed to replace the 5 you maybe able to do that but you would still have to get a set of shifters and derailleur to accommodate the 6 speed.
All in all it's not very cost effective thing to do with that old of a bike, if possible I would consider upgrading to a newer bike.
One other thing to think about is that old a bike if it's in good shape and you choose to sell, might be worth more to someone in its original state than being butchered.

A 7-10 speed cassette won't fit on a five speed. Modifying the hub to accept a 7-10 speed will make the wheel wider and not fit the frame with out stretching it. You will have chain and chainwheel size issues as well and at least a rear derailleur.
(And yes new shifters.)
Since you would be up for virtually a full group set I would suggest it may be time to up grade.
For a cheaper option
If you keep digging around ebay you could probably come up with the right five speed cassette (there are several). Or maybe the whole bike (it won't be dear) or a wheel. Your local bike shop may be able to salvage one given a bit of time
Good luck

Today's cassettes have one wider slot so they will not fit the old cassette hub on your bike, your hub's slots are all the same meaning it doesn't matter which position it is, it will slide on. Now you may find an old 6 speed compatible with yours.

anything less than an 8-speed hub is pretty old, like you said it'll be hard to find replacements for it.
if you upgrade to 7+ speed you'll need new shifters since there will be more gears to use. so you'd be best-off just buying a complete shimano/campy set of brakes/levers/cogs/cassette.
OR, you could drop all the gears and convert your bike to a fixie. you never have to worry about changing gears again!

i think a 7 speed would fit, but nothing else. if you want to use those extra gears, you need to get a new shifter for the rear, otherwise you can just use 5 gears. you might also need a new derailluer to be able to make the larger jump to the 6th and 7th cogs. take your bike to a shop and have a mechanic look it over and get his professional opinion. its kinda hard to tell without looking st the bike.
