Everyday suction-like sticking is 「吸い付く」; 「吸着」 also works but is more written, and is the term for gases or liquids adhering to a solid surface. For plain sticking, the general colloquial choice is 「くっつく」. The other verbs specify manner—flat, sticky, or people pairing up—while the written nouns 「付着」「粘着」「固着」「密着」「凝着」「癒着」「膠着」 each stress a different nuance. For the reverse, use 「剥離」, or 「脱着」 for technical desorption.
