it would be yo conozco a todos los..
yo means I meaning the conjugation would have to be conozco.
for your information, a conjugation is the adaptation of a er/ir 'to be' verb, to suggest the people performing the verb.
for example..
trabajar- to work
trabajO- i work
trabajas- you work
trabaja- he/she works
1. estoy, it explains that she is currently happy
2. es, explains the color of the brush
3. está, location of the brush
4. son, where they’re from
5. it should be están, but bc of the “a” after it confuses me, but it’d explain where they are
