Demas ... Crescens ... Titus

These are names of men. (See: rc://en/ta/man/jit/translate-names)

He loves this present world

Here "world" refers to worldly things as opposed to the things of God. Possible meanings are 1) he loves the temporary comforts of this world or 2) he is afraid he will die if he remains with Paul. (See: rc://en/ta/man/jit/figs-metonymy)

Crescens went ... and Titus went

These two men had left Paul, but Paul is not saying that they also "love this present world" like Demas.

Dalmatia

This is the name of a land region. (See: rc://en/ta/man/jit/translate-names)
