2 inductors can be combined in series to get a higher current rating and inductance?

Only second half of that statement is true.
It should be apparent that, since the current through both series inductors is the same, the current rating does not change.

No, the current rating will be the same as that for a single inductor.

Is "current" and "current rating" same meaning?

No.

Current = the number of amps which are flowing now.

Current Rating = The maximum number of amps which can flow through the device before it is damaged.

Two "300nH inductor in series" will having the same current rating as "one 700nH inductor"?

Am I correct?

It depends on their ratings - if one 300nH is the same current rating, then two in series will be as well.

How can we know the 300nH current rating?

Read it off the datasheet.

Thank you.

I am using 300nH (2222SQ-301_E), so the Irms value is 3.7.

so two 300nH in series, is also 3.7

If you have a problem understand this, you need to study how series and parallel circuits work.

If you wire them in parallel then the current can double but the inductance will half.
