Question

Find V1 using mesh and nodal analysis

Answer 1

Here is the Figure

Answer 2

are there any links as to how to interpret the components? what is 8i1...is that a fpga or a plc or something like that??

Answer 3

its the current flowing on 2 ohms resistor

Answer 4

If I interpret your diagram correct:
let top left node be Va, top right Vb, mid left Vd, mid right Vc, ground reference V=0 at bottom.
Vb-Va = 8i1
Va+16 = Vd
Vd = -i1*2
(-Va/4) + (-Vd/2) + (-Vc/2) = 3V1/4
Vc - Vb = V1
5 = V1/2 + Vc/4
Looks like 6 equations, 6 unknowns.
