Identifying Pipes
I have assumed that pipe 1 is for the shower, 2 is for the toilet, and 3 is for a vanity/sink, but I would like to make sure, and is there a way for me to make sure? As for pipes 4 and 5, I’m wondering if anyone could simply identify them and their use?

I would very much like to know why you're asking. If you're doing the work, STOP! Because you're not qualified.
These all look like drain or sewer lines. Your contractor has a floor plan that has already been determined and can't be changed. Water supply lines will determine the exact location of each appliance. I don't see them installed yet.

2" is code for a shower and when my DWV piping was replaced the plumber ran 2" for everything except the toilets.
For the OP - the pics look like new construction. Do you have the plans or a contractor?

1: Vanity/sink
2: Toilet
3: Shower (Should have a trap under the floor, but need to confirm)
4: is probably for a laundry tub, but it's hard to tell.
5: is the drain lines from upstairs and can't be used for much of anything in the basement in a code-compliant way.
There should also be a capped vent line in the ceiling in or around the bathroom that the vanity will connect to and should vent the whole bathroom group.

Zorfdt I’m not seeing any capped vent lines in the ceiling anywhere in the basement. Does this signify anything, and would you have a recommendation for confirming that #1 is vanity/sink, and #3 is shower? I’m hoping it is the other way around, but I’ll have no problem managing.

You must have a piped vent for a toilet so you'll need to look until you find it. Unfortunately I've seen it often omitted when purchasing the basement bath rough-in option.
If both #1 & #3 are 2" pipes (2 1/2" outside diameter) then they could be for the tub or vanity. As Zorfdt mentioned the shower one should have a trap under the floor while the vanity drain will not. Uncapping them and pouring in some water will confirm which has the trap.
