The most common substitutions for beginners are: power chord or easiest triad.

So, for the G minor:

|-------3----|

|-------3----|

|-------3----|

|------------|

|--5---------|

|--3---------|

C minor:

|-------3----|

|-------4----|

|-------5----|

|--5---------|

|--3--------|

|------------|

E-flat:

|------------|

|-------8----|

|-------8----|

|--8---8----|

|--6--------|

|------------|

B-flat:

|------------|

|-------3----|

|-------3----|

|--3---3----|

|--1---------|

|------------|

Hope that helps!

P.S. Keep working on barre chords. :)
