I'm making my garage into a living place and I put in a 50 amp line from my house to the garage. The garage has its own fuse box but I want to have an upstairs living area and a downstairs man-cave. I want to plug in a freezer, refrigerator and a couple of AC's and of course upstairs would have a TV and a computer. Am I going to have enough amps or am I going to be blowing the fuse box often?

This is what you would use for a regular house receptacle in the us.
For the outside use a "inlet receptacle"
Then you need a cover for it while not in use.
Ideally a bubble cover or an in-use cover would be best. If I find one I'll edit this.
After you get all this and you will need for the inside a cut-in box, receptacle and cover. A piece of 12/2 romex or NM to go between, wiring the black wire to the brass screws, the white wire to the silver screws and green wire to green screw.
Good question, but pause to think: What if all your wiring was in EMT metal conduit? (In which the conduit is the ground). There'd be no choice to bond the grounds, and thus, it is OK.
This question is even easier since you are working out of a sub-panel, which already has its ground bonded to the main panel; that is, one ground rod for the whole house. I have a facility where the 120/240v is served out of two main panels, each with its own supply transformer and its own ground. Circuits from both main panels go into a spiderweb of EMT, and while the neutrals never cross, the EMT certainly does, which means the ground does. What's more, the EMT is attached to an all steel building via girder clamps that are entirely made of metal. It would be impractical to separate the grounds. All this to say: If I am allowed to mix grounds, you certainly are.

Look at the published ratings for each of the specific appliances you want to run simultaneously, and add them up. You'll have to do this yourself; we don't know which units you're interested in, and in fact it may affect which ones you purchase.
If the sum is more amps than the breaker will permit, the breaker or fuse will eventually blow when everything happens to make its peak demand simultaneously.
