Beginner questions on some SMD components in phone motherboard
They do look like rather "gigantic" (for phone integration) caps, yes. But they could also be something else – like a whole filter. But, seeing them in this context, yeah, caps.
An SMD 0201 component. That's pretty much all one can say with certainty. From here, it looks like it might be some resistor (totally unknown value), but it might also be a low-value capacitor.
Probably yes, but again, since one can't look inside SMD components... But, if they are, then the closest IC is a switch-mode power supply controller (or has one built in). If you know that's the case: here's your inductors.
an SMD resistor, capacitor, miniature ferrite bead, diode, or other component.
