Yes, Sony said they'll continue growing via acquisitions. But in the mid to long term, pretty likely after they sell most of their banks division in 2-3 years from now.
Does inorganic mean someone that’s not second party?
Organic = to grow a company revenue by focusing on what you already have: tweaking your product, hiring people, improving your marketing or manufacturing methods, hiring some people, to make new products with the team you aready have... basically selling more because you improve the product or things you already make
Inorganic = to grow via acquisitions, you buy a company or companies who make other products, so you add their revenue and profit on top what you already have
When applied to gaming, 'organic' would be what Sony did of hiring people to grow all their teams, to make movie/tv adaptations of their IPs with other divisions, to expand their IPs to PC and mobile, to acquire teams who already were basically only working for them.
'Inorganic' would be acquisitions like Double Fine, Bethesda, ABK, Bungie or EVO, companies not too attached to them just to secure their catalog and get their revenue and profits. It could include big publishers like Capcom or Square, small publishers like Devolver or Annapurna, big devs like From Soft or CD Projekt, small devs like Blue Twelve, Sloclap or Emberlab, random support/mobile/porting/VR teams or companies who make anything else as could be accesories, eSports stuff or internal tech for things like cloud or VR. To buy companies of any type and size who aren't super attached to them.

Can they afford Square or Capcom?
Both, and at the same time.
But I wonder if inorganic would rule out Square considering their already close relationship.
Capcom or Square or any 3rd party company would count as inorganic. Same goes with 2nd party studios who not only work with them.
Sony could afford to acquire both Square and Capcom, but to do so these companies should be open to sell, and particularly to sell to Sony. And Sony would need to want to buy.
Sony said they'll continue acquiring but not this fiscal year, that they'll take their time: they spent the acquisitions and investments budget they had for this year in other things and mentioned they'll continue with acquisitions in the mid to long term. And also mentioned that will branch out and sell most of their banks division to use that money for acquisitions (a process that will take 2-3 years).
