The six-membered cyclic structure of glucose is called pyranose structure ( $\alpha$ - or $\beta-$ ), in analogy with pyran which is a cyclic organic compound with one oxygen and five carbon atoms in the ring.
Hence, ring $(i)$ is pyranose.
The ring $(i)$ is pyranose with $\alpha$-glycosidic linkage which means the oxide linkage which connects the monosaccharide units in polysaccharide below the plane.
