So i've been going to gym for about a month and my friend thinks (we usually do 2 parts of body for example legs and back or triceps and chest) that it's not good to do for example biceps and legs or chest and back in one workout. Is he right or wrong?
To make it simple, is it important what two parts of body i do per workout or not? Sorry for bad English.

He's right. Only workout one muscle groups or close groups.
For example, here's my split:
Tuesday- chest and triceps
Wednesday- back and biceps
Thursday- glutes, abs, calves
Friday- arms and shoulders
You won't see a big difference in strength if you're hitting all your muscles at once instead of really focusing on them separately once or twice max per week.1

Yes. Just because a workout is geared towards a muscle group does not mean it is the only muscle working. Other muscles are involved, but its just that some work harder than others. If you work out too many muscle groups, or do odd combinations, you are not getting the most out of the workout. The goal is to work muscle groups where 1 muscle group uses the other muscle group to a small degree, like how bench presses also work triceps a bit).
Pairing muscle groups that compliment each other is ideal, and over the course of a week, spacing certain muscle groups certain days apart also helps. I stick to a 5 day workout schedule, so I usually have one muscle group per day (Leg, back, shoulder, arms, chest)
Chest + Triceps are good (i. e., bench presses use triceps)
Biceps +Triceps are good
Chest + Biceps are NOT good (biceps are a pull muscle, triceps and chest are push muscles)
Legs should have its own, separate day.
Back + shoulders is good
Back + biceps is good (biceps and back are pull muscles)
Abs can be paired with really any workout, but I'd recommend it with back or legs, but most definitely with cardio. Most people run for cardio, and abs are built better during a run than during a crunch (sprint intervals give really unbelievable ab results)
Finally, after working 2 muscle groups, you want to give them time to heal properly. This is done by not working muscle groups that use the ones you just worked out to any degree. So you might start with legs and abs, chest and triceps (push), rest day, biceps and back (pull), shoulder and abs, arms, then rest day.2
